Answer:
It takes 75 years for the investment to quadruple in value
Step-by-step explanation:
Simple Interest
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:
4% simple interest per year, so I = 0.04.
Quadruple:
t when T = 4P.
The interest earned is:
Now we find the time.

Answer:
Step-by-step explanation:
we have
---> First equation
--->Second equation
we know that
To subtract the 2nd equation from the first, negate all three of the second equation terms: -7x-8y=6
and then adds this result with the first equation
so
Answer:
y = 1/2x
Step-by-step explanation:
Substitute the given information into the equation y = mx + b
<em>Your goal is to find what b is</em>
Obviously, the point given --> (4, 2) is the x and y.
The m is the slope (1/2)
